SGP/QCRAD/E27 - Reprocess: Incorrect calibration coefficients

Logger reverted to previous years configuration, possibly due to power outage and 
non-current logger program in storage module.  Note, the tracker had failed during this period as 
well.

The configurations are as follows:
Correct S/N and coefficients for this station during this time
Diffuse PSP:   33268F3
PSP-US:        30811F3
NIP:	       29578E6
PSP-DS:        30903F3
Diffuse PSP: 118.49 W/(m^2*mV)
PSP-US:      116.66 W/(m^2*mV)
NIP:	     123.30 W/(m^2*mV)
PSP-DS:      128.92 W/(m^2*mV)

Incorrect S/N and coefficients applied during this time range.

Diffuse PSP: 111.68 W/(m^2*mV)

NIP:	     111.03 W/(m^2*mV)
PSP-DS:      104.15 W/(m^2*mV)

Data must be reprocessed for all shortwave instruments; longwave instruments are 
unaffected. The following corrections must be applied:

down_short_diffuse_hemisp(new) = down_short_diffuse_hemisp(old) * 118.49/111.68
up_short_hemisp(new) = up_short_hemisp(old) * 116.66/111.85
short_direct_normal(new) = short_direct_normal(old) * 123.30 / 111.03
down_short_hemisp(new) = down_short_hemisp(old) * 128.92 / 104.15

Reference instrument DQR D090521.1
